Commit efc6b6f6c311 ("udp: Improve load balancing for SO_REUSEPORT.")
in net conflicts with
Commit 72f7e9440e9b ("udp: Run SK_LOOKUP BPF program on socket lookup")
in bpf-next.
Commit 4a0e87bb1836 ("udp: Don't discard reuseport selection when group
has connections")
also in bpf-next reduces the conflict.
Further simplify by applying the main change of the first commit to
bpf-next. After this a conflict remains, but the bpf-next side can be
taken as is.
Now unused variable reuseport_result added in net must also be
removed. That applies without a conflict, so is harder to spot.
